EQUIPMENT FOR CARGO
CARGO SPACE DEFINITION
TYPE OF CARGO SPACES
Epoxy coated cargo tanks integrated in the structure separated by longitudinal and transverse corrugated bulkheads and integratedt slop tank at fore of cargo space.
NUMBER OF CARGO COMPARTMENT
10 Cargo Tanks + 1 Integrated Slop Tank
MAX CARGO DENSITY
1.54 t/m³
DECK CRANES FOR CARGO
GURDESAN, Cargo Hose Crane, SWL 5t, 12 m / Provision Crane, SWL 2t, 7 m
CARGO SYSTEM
Cargo system is designed so that 11 different substances can be loaded/ unloaded at the same time. Also a unique substance can be loaded / unloaded to /from all tanks by means of the two common line located aft and fore of cargo manifold.
Cargo discharge system of the ship is capable of discharging six (6) tanks at the same time in full capacitiy.
CARGO DISCHARGE CAPACITY
Cargo discharge system of the ship is capable of discharging six (6) tanks at the same time in full capacitiy.
CARGO PUMPS
MARFLEX, 10 x 150 m³/h, 100mlc, 1 cSt / 1 x 80 m³/h
CARGO PIPES & FITTINGS
Cargo pipes are class II type mild steel pipe. The connections to be of butt welded if possible. The pipelines to be of through cargo tank inside. The pipelines to be arranged with sufficient expansion possibilities.
CARGO SYSTEM VALVES
DANFOSS, Remote Operated Hydraulic Valves
SEPARATE STRIPPING SYSTEM
There are two kinds of stripping procedures applying for this vessel. Cargo tanks 6P&S, 5P&S,4P&S which are located aft of the manifold and cargo tanks 3P&S, 2P&S, SLOP which are at fore of the manifold. Stripping is done by using compressed air or nitrogen when substances can not face to contact the air ie oxygen. DN 25 x Sch 10s stainless steel seamless 316L 1.4404 for stripping pipes are used in stripping system.
FREEZING, REFRIGERATING & HEATING SYSTEM FOR CARGO
Stainless steel heating coils
INERT GAS SYSTEM
Nitrogen system is designed so that to fill 95% ullage volume of all cargo tanks and slop tank at the same time. Nitrogen main pipes are connected to each tank cargo access hatch by means of the flexible hoses. System contain 10 pieces 50 lt, 200 bar nitrogen tube, control cabinet (include reducer, safety, non return valves.), flexible hoses. The cargo tank inlet pressure of nitrogen gas is 0.13 bar. Nitrogen tubes control cabinet and flexible hoses will be keep in Nitrogen room located main deck above the pump room .System is also used for stripping and purging purpose as well.
CARGO VENTILATION SYSTEM
PV valves setting pressure is 2000 mmWG for pressure, -350 mmWG for vacum. The lines between PV valves and tanks are so arranged as to permit their self draining to the tanks.Pipe connections are to be full penetration butt welded type.
TANK CLEANING SYSTEM
Each cargo tank to be fitted with two tank cleaning hatches for tank portable tank cleaning machines. Tank cleaning hatches also to be used for ventilation gas freeing fans. Tank cleaning pump to be centrifugal, electric driven capacity 40 m³/h, 10 bar.
